Overview

Making a challenge sim? Want to make a new sim/family but lacking the inspiration? Want to select a random job for a sim, or a random skill? Whether they should be a supernatural? This download allows you to randomize sims and/or their properties quickly and easily using a graphical user interface. Simply open the randomizer in your web browser, select the aspects you would like to randomize, and you're set to go.

Note: This download is not an in-game download, but rather a stand-alone utility. It does not go in your Mods folder, and it does not automatically make random sims/families for you. It's more of an easy-to-use electronic die, if you will. It shows you the randomization results, which you can then take note of and use when making your sim/family.

The TS4 Sim Randomizer is based on The Sim Randomizer for TS2, which I made a few years back with Phaenoh's help. This is essentially the same tool, but for TS4. It uses a very slight adaptation of Phaenoh's layout from 2013, and it's uploaded with permission.

Update: February 9, 2018: updated for patch PC 1.39.74.1020 / Mac 1.39.74.1220, which added 10 new skin tones. The new version has a small code update to account for the increased amount of skins, and the skin icons are updated to match the post patch situation. The skins considered unnaturals are now numbers 27 through 35. Note: the new skintones were added in the middle of the swatch in the game, so if you use the old version of this randomizer, the numbers given in the icons no longer correspond to the order of the swatch. By redownloading, you can avoid this inconvenience, as well as randomize between all the skins currently in the game.

Update: May 12, 2018: updated for the Jungle Adventure pack, which added two new Aspirations and two new Skills.

Update: May 29, 2018: fixed a bug that caused the "previously existing" option within the gender preference feature to be disregarded and the gender selected always being female with this option selected.

Update: September 29, 2018: updated for the Seasons pack, which added one new career and one new skill. Added a new feature that allows you to randomize whether or not your sim has a tattoo. Thanks to Atreya for the suggestion!

Installation and use

There is no need to install this download. Simply extract the .rar file where you want it on your computer, and you should get a folder with: a .html file, a readme file and a folder with images in it. To use the randomizer, simply open the .html file in your web browser (tested on Firefox, Safari, Chrome and Edge*).

When you open the randomizer in your browser, you have the feature selections on the left, and on the right are eight empty boxes for sims to be randomized.** You use the program by first filling in the features you want to randomize, and the pressing the "Randomize" button. The resulting sims will be shown as icons and associated text. You can either write down the results, or if you play in a window, keep the randomizer open when you start the game and make your sims.

* Note 1: The randomizer seems to work fine on Edge, but it's unlikely work on IE. I'm on Windows 10 so I can't test that easily. It might work as such, but the layout will probably break.

** Note 2: If your screen or browser window is small, the selections may be at the top and the empty sims boxes at the bottom. Unlike the original TS2 randomizer, this one is built to adapt to your screen size. It's prettiest on a big screen (in my opinion anyway), but at least it doesn't look completely broken when on a smaller screen.

Features and options

The following are the features and options of The Sims 4 Randomizer.

General options

Which packs do you have?

Choose the Expansion, Game and Stuff Packs that you're playing with in order to get correct randomization results according to your setup. If a pack is not listed here, it means it doesn't have an effect on the features randomized.

How many sims would you like to randomize?

There are two options: #sims and Random (1 to 8 sims). With the first option, you can select the number of sims to be randomized by typing the desired number in the text field. The minimum number of sims to be randomized at once is 1 and the maximum is 8 - the biggest default family size in the game. If you try to feed in a number that is smaller than one or bigger than eight, the program will use the values 1 or eight, respectively. With the second option, you can choose to let the program decide the number of sims for you: you will be equally likely to get any number of
sims between 1 and 8.

Would you like to place restrictions on ages randomized?

The next three options have to do with restrictions on the family members.

With Min 1 young adult to elder selected, the randomizer will make sure that there is at least one sim who is a young adult or older. This is done by forcing the first sim randomized to be one of these ages. With this option selected, you get families that you should be able to make directly in CAS. Selected by default.

With Min 1 teen to elder selected, the randomizer will force the first sim to be a teen or older. You can't make a family like this directly in CAS, but with a little creativity (and, ahem, a little cruelty), such a family can be played.

With Allow all selected, no age restrictions are placed on the sims randomized. This means that you could end up with sims that are only toddlers or children. This option is of little use in regular gameplay, as toddlers and children cannot survive on their own, but it's provided for character creation purposes and in case some players might have a hack to allow young sims to survive on their own.

Note: These restrictions apply regardless of what your family size is. For example, if you have restricted the first sim to be between young adult and elder and only chosen to randomize one sim, this sim will be one of those ages.

Randomize adult properties for young sims?

Several aspects that can be randomized aren't yet relevant to young sims or are different for them: in personality, the full 3 traits are only given to young adult sims and older, aspirations and skills are different for different ages, and careers are only relevant for teens and up. If you choose this option, young sims will be given the aspects relevant to their age as well as their future ages. For example, with this option selected, a child sim would receive both a child aspiration and an adult aspiration.

Genetic aspects

Here you can select the genetic aspects that you would like to randomize for your sims, and some related options. All genetic aspects are selected by defaut.

Age

Each of the six options, toddler, child, teen, young adult, adult and elder, are equally likely.

Gender

The two options available in the game, male and female, are equally likely.

In addition, there is one option: Custom gender (on by default), where you can give a percentage (defaults at 10). With this option selected, each randomized sim will have an x percent chance to receive a custom gender, where x is the percentage that you've given. The remaining sims will be simply male or female. The custom gender properties in TS4 are as follows:

physical frame (feminine or masculine)

clothing preference (feminine or masculine)

pregancy (can get pregnant, can get others pregnant or neither)

can use the toilet standing up (yes or no)

For each of these properties, each of the possible choices are equally likely. The only exception is that if the sim receives a custom gender, it is forced to be truly custom. That is, you cannot get a "custom" female sim that has a feminine physical frame, a feminine clothing preference, that can get pregnant and that can't use the toilet standing - because that wouldn't actually be custom. The same kind of restriction applies to custom male sims, of course.

Skintone

The game has 25 different skintone options available, and for the purposes of the randomizer, they have been given numbers in the order that they appear in the swatch in CAS. There are two options: Naturals and Unnaturals, Naturals is selected by default. They control which skintones can be selected for your sim. Skintones from 1 to 26 are considered "natural" tones, the kind that you'd expect to see on human looking sims, and the ones from 27 to 35 are "unnatural", such that could be used on fantasy sims. You can choose one of these options, or if you want to pick from all available options, check both of these boxes. Obviously, to get a skintone for your sims, you must select at least one, or you won't have any options to pick from! Each option from those selected is equally likely.

Hair color

The game has 18 hair color options available, numbered in the CAS swatch order. There are two options: Naturals and Unnaturals, Naturals is selected by default. Hair colors from 1 to 11 as well as 17 and 18 are considered "natural", and the ones from 12 to 16 are "unnatural". You must choose at least one to be able to get a hair color. Each option from those selected is equally likely.

Eye color

The game has 18 eye color options available, again numbered in the CAS swatch order. There are two options: Naturals and Unnaturals, Naturals is selected by default. Eye colors from 1 to 16 are considered "natural", and colors 17 and 18 are "unnatural". Again it makes no sense to deselect both options, and each option is equally likely.

Voice

There are six options available in the game: brash, clear, lilted, melodic, sweet and warm. Each of these options is equally likely.

Walking style

There are 10 options available in the game: bouncy, creepy, default, feminine, goofy, perky, sluggish, snooty, swagger and tough. Each of these options is equally likely.

Personality

The personality of a sim consists of traits, and the kind and amount of traits depends on the age of the sim: toddlers get one trait from a separate pool of toddler traits, and the older ages get traits from the adult pool of traits. Children get one trait, teenagers two traits, and young adults and older get three. What traits are available to be selected depends on the packs that you have installed. In addition, some traits are incompatible with each other: you cannot, for example, make a Family Oriented sim who also Hates Children. For each age group, the appropriate kind and number of traits are randomized, except if you have the Randomize adult properties for young sims selected: in that case, a young sim will receive both current and future traits.

There is one option, For an existing sim? If you select this, the randomizer knows that you want to randomize a personality for an existing sim (rather than a completely new one). If you select this, you must also give an age for your sim with the radio buttons below, so that the randomizer knows how many traits to randomize for your sim. If your sim already has one or two adult traits, select them from the two Existing traits dropdown menus, so that you won't get the same traits twice and also won't get a trait that is in conflict with an existing one.

If you are randomizing for a born-in-game sim and want to take their parents' traits into account when randomizing, fill in the parent traits into the Parent traits drop down menus. Any traits that you specify here will be twice as likely as any other trait. Of course, if you have already marked your sim as having a trait that is in conflict with one of the parent traits given, that parent trait still can't be selected in randomization.

Example: Your sim previously has the Good trait, and one of the parents has the Evil trait. Now normally, a trait that you mark a parent to have would be twice as likely as any non-parent trait, but because the Evil trait is in conflict with an existing trait and the game won't let you select it, it also can't be randomized for your sim.

Visual aspects

Here you can select visual aspects of your sims to be randomized. All except the Supernaturals aspect are selected by default.

Hats

Whether or not your sim wears a hat. You can define the chance of getting a sim who wears a hat with % chance of hat, which defaults at 20.

Glasses

Whether or not your sim wears glasses. Again, you can define the chance of glasses by setting % chance of glasses. Defaults at 20.

Tattoos

Whether or not your sim has a tattoo. As before, you can define the chance of tattoos by setting % chance of tattoo. Defaults at 20.

Supernaturals

This aspect determines whether your sim is a supernatural, and if so, what kind. With the current set of packs, there are two kinds of supernaturals: aliens and vampires. In addition to being able to set the % chance of getting a supernatural, you can choose which kinds of supernaturals you want to get. Note that in order to get any supernatural sims, you must have selected at least one of the supernatural kinds!

The randomization works as follows. First, it determines whether your sim should be a supernatural, according to the chance you gave. If not, the sim will be a human. If they are a supernatural, each kind of supernatural that you selected (and that's possible according to your pack selection) is equally likely.

Both of the current supernatural kinds should be possible for all ages, so there are no age restrictions here.

Ambition aspects

Here you can randomize aspects having to do with your sim's ambition. Aspiration is selected by default, the rest are not.

Aspiration

Your sim's aspiration. Sim children have a separate pool of aspirations, and which adult aspirations are possible depends on your pack configuration. Children will receive a child aspiration and teens and up will receive an adult aspiration according to your selected packs. Each possible choice is equally likely.

If you've selected the Randomize adult properties for young sims option, toddlers and children will receive both child and adult aspirations.

Career

A career for your sim is randomized according to your selected packs. How you interpret this career is up to you: it could be a career your sim has to maximize, a career they must work at least for a while, or whatever else you decide it to mean. This aspect has the option with branch: if you select it, instead of just randomizing a career, you will be given a career with also the branch choice determined, assuming that the career you get has branches.

Teens have a separate pool of part time jobs, so if your sim is a teen, they will receive one of those. With the Randomize adult properties for young sims option, toddlers, children and teens will receive both a teen job and an adult career.

Skill

As TS4 and its various packs introduce a large number of skills, it seems unlikely that a single sim would be proficient at all / a substantial amount of them. Hence, this aspect randomizes a single skill for your sim. Again, you may interpret this skill as you wish.

Toddlers and children both have their special pools of skills, and teenagers and up use the adult skills. What adult skills are available depends on your pack configuration.

A single age appropriate skill is randomized for your sim, with all the available choices being equally likely. If you check the Randomize adult properties for young sims option, your sim will receive both the current and any future skills. That is, with the prerandomization option, a toddler sim would receive a toddler skill, a child skill and an adult skill.

Attraction aspects

Here you can randomize attraction aspects for your sim, currently only containing gender preference, which is not selected by default.

Gender preference

By selecting this aspect, you can randomize your sim's gender preference. This is implemented with the options readily available in the game: straight, gay, bi and a. You can set the ratios of the
different preferences using the % straight, % gay, % bi and % a -text fields. This aspect also includes the option Previously existing. You can select this option if rather than randomizing a brand new sim you want to randomize the gender preference of an existing sim. In this case, you need to specify the sim's gender, as it is used in the preference calculations and displaying the result if your sim ends up straight or gay.

Note: Despite the %-signs on the user interface, the program does not in fact force you to sum the total of your ratios to 100, but will use whatever the total of your ratios actually is. It is thus up to
you to make sure the ratios are what you want them to be. Example: you want to increase the percentage of gay sims in your neighborhood, so you set the % gay field to 15 instead of the default 10, but do not lower the number for another orientation. This means that your total is now 75 + 15 + 10 +5 = 105, not 100. This is just fine by the randomizer, which will now take the probability of your sim being gay to be 15/105, but this may not be what you intended.
